I sorta agree about the scent lock stuff until an old bear hunter neighbor told me how he has success. He swears by hip (rubber) boots and a military surplus type chemical suit... This guy is worth listening too because of some 30 years of bear hunting he has taken 17. Three of these bears were +400 pound bears. So maybe he has something to this set up.... He is careful about wind direction and path in and out of his hunting locations. I think no matter what you do or wear.....the wind and thermals can bust us even when we think we did all we could to be covert.
